           (b) Issuance of Shares. If a Stock Award should expire, become unexercisable, be forfeited or otherwise terminate for any reason without having been exercised in full, the then unpurchased or forfeited Shares that were subject thereto shall, unless the Plan shall have been terminated, become available for future grant under the Plan; provided, however, that if a Stock Award is canceled, forfeited or treated as having been canceled for purposes of Section 162(m) of the Code, then the canceled Stock Award shall count against the maximum number of shares for which a Stock Award may be granted to any person under the terms of the Plan.

The aggregate number of Shares that may be issued pursuant to the exercise of Incentive Stock Options granted under this Plan shall not exceed 79,370,100, which number shall be calculated and adjusted pursuant to Section 12 only to the extent that such calculation or adjustment will not affect the status of any option intended to qualify as an Incentive Stock Option under Section 422 of the Code.

      4. Administration of the Plan.

           (a) Procedure. The Plan shall be administered by the Board of Directors. The Board of Directors may appoint a Committee consisting of one or more members of the Board of Directors, to administer the Plan on behalf of the Board of Directors, subject to such terms and conditions as the Board of Directors may prescribe. In such event, any references in the Plan to the Board of Directors shall be deemed to refer to the Committee. To the extent required to satisfy the requirements of Rule 16b-3 or Section 162(m) of the Code, the Committee shall consist of two or more “Non-Employee Directors” (i.e., a director who is receiving no compensation from the Company other than for service on the Board of Directors or who does not receive such additional compensation which exceeds the limits specified in the definition of such term under Rule 16b-3 and otherwise meets the requirement under Rule 16b-3 for “non-employee directors”) or “Outside Directors” (i.e., a director who is not either a current or former officer of the Company nor a current employee of the Company, and who is receiving no compensation from the Company other than for service on the Board of Directors or who does not receive such additional compensation which exceeds the limits specified in the definition of such term under Section 162(m) of the Code). Once appointed, the Committee shall continue to serve until otherwise directed by the Board of Directors. From time to time the Board of Directors may increase or decrease the size of the Committee and appoint additional members thereof, remove members (with or without cause), and appoint new members in substitution therefor, fill vacancies however caused and remove all members of the Committee, and thereafter directly administer the Plan. Notwithstanding anything in this Section 4 to the contrary, at any time the Board of Directors or the Committee may delegate to a committee of one or more members of the Board of Directors the authority to grant Stock Awards to all Employees and Consultants or any portion or class thereof. Members of the Board of Directors who are either eligible for Stock Awards or have been granted Stock Awards may vote on any matters affecting the administration of the Plan or grant of any Stock Awards pursuant to the Plan, except that no such member shall act upon the granting of a Stock Award to himself, but any such member may be counted in determining the existence of a quorum at any meeting of the Board during which action is taken with respect to the granting of Stock Awards to him or her.

           (b) Powers of the Board. Subject to the provisions of the Plan, the Board shall have the authority, in its discretion: (i) to grant Stock Awards under the Plan; (ii) to determine the exercise or sales price per share of Stock Awards to be granted, which exercise price shall be determined in accordance with Sections 8(a) and 10(c) of the Plan, as applicable; (iii) to determine the Employees or Consultants to whom, and the time or times at which, Stock Awards shall be granted, the number of Shares to be represented by each Stock Award, and the terms of such Stock Awards; (iv) to interpret the Plan; (v) to prescribe, amend and rescind rules and regulations relating to the Plan; (vi) to determine the terms and provisions of each Stock Award granted (which need not be identical) in accordance with the Plan, and, with the consent of the holder thereof with respect to any adverse change, modify or amend each Stock Award; (vii) to accelerate or defer (the latter with the consent of the Participant) the exercise date and vesting of any Stock Award; (viii) to authorize any person to execute on behalf of the Company any instrument required to effectuate the grant of a Stock Award previously granted by the Board; and (ix) to make all other determinations deemed necessary or advisable for the

administration of the Plan. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan or in any Stock Award Agreement, in a manner and to the extent it shall deem necessary or expedient to make the Plan fully effective.

           (c) Effect of Board’s Decision. All decisions, determinations and interpretations of the Board shall be final and binding on all Participants and any other holders of any Stock Awards granted under the Plan.

      5. Eligibility. Stock Awards may be granted only to Employees or Consultants. An Employee or Consultant who has been granted a Stock Award may, if he or she is otherwise eligible, be granted an additional Stock Award.

          Incentive Stock Options may only be granted to Employees. The aggregate Fair Market Value (determined at the time the Option is granted) of the stock with respect to which Incentive Stock Options are exercisable for the first time by such individual during any calendar year (under the Plan or under any other incentive stock option plan of the Company or any Parent or Subsidiary of the Company) shall not exceed $100,000. To the extent that the grant of an Option exceeds this limit, the portion of the Option that exceeds such limit shall be treated as a Nonstatutory Stock Option.

          The Plan shall not confer upon any Participant any right with respect to continuation of employment or consultancy by the Company or any Affiliate, as applicable, nor shall it interfere in any way with the Participant’s right or the Company’s or any Affiliate’s right to terminate the Participant’s employment at any time or the Participant’s consultancy pursuant to the terms of the Consultant’s agreement with the Company or any Affiliate.

      6. Term of the Plan. The Plan became effective upon its adoption by the Board of Directors. Subsequently amended, the Plan shall continue in effect until March 16, 2021 unless sooner terminated under Section 14 hereof.

      7. Term of Option; Vesting Provisions.

           (a) Option Term. The term of each Option shall be seven (7) years from the date of grant thereof or such shorter term as may be provided in the applicable Stock Option Agreement. However, in the case of an Incentive Stock Option granted to an Employee, who immediately before the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option shall be five (5) years from the date of grant thereof or such shorter time as may be provided in the applicable Stock Option Agreement.

           (b) Vesting Provisions. The terms on which each Option shall vest shall be determined by the Board in its discretion, and shall be set forth in the Stock Option Agreement relating to each such Option. Without limiting the discretion of the Board, vesting provisions may include time-based vesting or vesting based on achievement of performance or other criteria. Performance criteria may, but need not, be based on Qualifying Performance Criteria. The provisions of this Section 7(b) are subject to any Option provisions governing the minimum number of Shares as to which an Option may be exercised.

      8. Option Exercise Price and Consideration.

           (a) Exercise Price. The per Share exercise price for the Shares to be issued pursuant to exercise of an Option shall be such price as is determined by the Board, but shall be subject to the following:

                (i)  In the case of an Incentive Stock Option:

                     (1)  Granted to an Employee who, immediately before the grant of such Incentive Stock Option, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant.

                     (2)  Granted to any Employee to whom Section 8(a)(i)(1) hereof is not applicable, the per Share exercise price shall be no less than 100% of the Fair Market Value per Share on the date of grant.

                (ii)  In the case of an Option granted on or after the effective date of registration of any class of equity security of the Company pursuant to Section 12 of the Exchange Act and prior to six months after the termination of such registration, the per Share exercise price shall be not less than 100% of the Fair Market Value per Share on the date of grant.

                (iii)  Notwithstanding the provisions of this Section 8(a), an Option (whether an Incentive Stock Option or Nonstatutory Stock Option) may be granted with an exercise price lower than set forth in this Section 8(a) if such Option is granted pursuant to an assumption or substitution for another option in a manner satisfying the provisions of Section 424(a) of the Code.

           (b) Consideration. Subject to applicable law, the consideration to be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall be determined by the Board and may consist entirely of cash, check, shares of Common Stock having a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised, or any combination of such methods of payment, or such other consideration and method of payment for the issuance of Shares as may be determined by the Board. In making its determination as to the type of consideration to accept, the Board shall consider if acceptance of such consideration may be reasonably expected to benefit the Company.

           (c) No Repricing without Stockholder Approval. Other than in connection with a change in the Company’s capitalization (as described in Section 12), the Company shall not, without stockholder approval, (i) reduce the exercise price of such Option, (ii) exchange such Option for cash, another Stock Award or a new Option with a lower exercise price or (iii) otherwise reprice such Option.

      9. Exercise of Options.

           (a) Procedure for Exercise; Rights as a Stockholder . Any Option granted hereunder shall be exercisable at such times and under such conditions as determined by the Board, including performance criteria with respect to the Company and/or the Participant, and as shall be permissible under the terms of the Plan.

          An Option may not be exercised for a fraction of a Share.

          An Option shall be deemed to be exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Option by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been received by the Company. Full payment may, as authorized by the Board, consist of any consideration and method of payment allowable under Section 8(b) of the Plan. Until the issuance (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company) of the stock certificate evidencing such Shares, no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 12 of the Plan.

          Exercise of an Option in any manner shall result in a decrease in the number of Shares that thereafter may be available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised.

           (b) Termination of Status as an Employee or Consultant. If a Participant ceases to serve as an Employee or Consultant for any reason other than death, the Participant may, but only within such period of time ending on the earlier of (i) three (3) months (or such other period of time as is determined by the Board) after the date the Participant ceases to be an Employee or Consultant or (ii) the expiration of the term of the Option, exercise the Option to the extent that the Participant was entitled to exercise it at the date of such termination. To the extent that the Participant was not entitled to exercise the Option at the date of such termination, or if the Participant does not exercise such Option (which the Participant was entitled to exercise) within the time specified herein, the Option shall terminate.

           (c) Death of Participant. In the event of the death of a Participant:

                (i)  during the term of the Option who is at the time of the Participant’s death an Employee or Consultant and who shall have been in Continuous Status as an Employee or Consultant since the date of grant of the Option, the Option may be exercised at any time during the period ending on the earlier of the date that is three (3) months (or such longer period of time as determined by the Board) following the date of death or the date the Option would otherwise terminate, by the Participant’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent of the right to exercise that would have accrued had the Participant continued living three (3) months (or such longer period of time as determined by the Board) after the date of death. Any and all Options that are not exercised during such period shall terminate as of the end of such period; or

                (ii)  within one (1) month (or such longer period of time as determined by the Board) after the termination of Continuous Status as an Employee or Consultant, the Option may be exercised, at any time during the period ending on the earlier of the date that is three (3) months (or such longer period of time as determined by the Board) following the date of death or the date the Option would otherwise terminate, by the Participant’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent of the right to exercise that had accrued at the date of termination. Any and all of the deceased Participant’s Options that are not exercised during such period shall terminate as of the end of such period.

      10. Incentive Stock and Restricted Stock Units.

           (a) General. Incentive Stock is an award or issuance of shares of Common Stock under the Plan, the grant, issuance, retention, vesting and/or transferability of which is subject during specified periods of time to such conditions (including continued service or performance conditions) and terms as the Board deems appropriate. Restricted Stock Units are awards denominated in units of Shares under which the issuance of Shares is subject to such conditions (including continued employment or performance criteria) and terms as the Board deems appropriate. Unless determined otherwise by the Board, each Restricted Stock Unit will be equal to one Share and will entitle a Participant to either the issuance of Shares or payment of an amount of cash determined with reference to the value of Shares. The Board may specify that the grant, vesting or retention of any or all Incentive Stock and/or Restricted Stock Units is intended to satisfy the requirements for “performance-based compensation” under Section 162(m) of the Code. To the extent that any Incentive Stock and/or Restricted Stock Unit Award is designated by the Board as “performance-based compensation” under Section 162(m) of the Code, (i) the performance criteria for the grant, vesting or retention of any such Incentive Stock and/or Restricted Stock Unit Award shall be a measure based on one or more Qualifying Performance Criteria selected by the Board, specified at the time the Incentive Stock and/or Restricted Stock Unit Award is granted, and shall be a preestablished goal under Treasury Regulation Section 1.162-27(e)(2)(i), (ii) the Board shall certify the extent to which any Qualifying Performance Criteria has been satisfied, and the amount payable as a result thereof, prior to payment of any Incentive Stock and/or Restricted Stock Unit Award that is intended to satisfy the requirements for “performance-based compensation” under Section 162(m) of the Code, and (iii) the award shall comply with all other applicable requirements relating to “performance based compensation” under Section 162(m) of the Code. To the extent a performance-based award is not intended to satisfy the requirements for “performance-based compensation” under Section 162(m) of the Code, the performance criteria for the grant, vesting or retention of any such Incentive Stock and/or Restricted Stock Unit Award may be a measure based on one or more Qualifying Performance Criteria selected by the Board, or any other criteria deemed appropriate by the Board.

           (b) Incentive Stock Agreement; Restricted Stock Unit Agreement. Each Incentive Stock Agreement and Restricted Stock Unit Agreement shall contain provisions regarding (i) the number of shares of Common Stock subject to such award or a formula for determining such number, (ii) the purchase price of the Shares, if any, and the means of payment for the Shares, (iii) the performance criteria, if any, and level of achievement of these criteria

that shall determine the number of Shares granted, issued, retainable and/or vested, (iv) such terms and conditions on the grant, issuance, vesting and/or forfeiture of the Shares as may be determined from time to time by the Board, (v) restrictions on the transferability of the Shares and (vi) such further terms and conditions in each case not inconsistent with the Plan as may be determined from time to time by the Board. Shares of Incentive Stock may be issued in the name of the Participant and held by the Participant or held by the Company, in each case as the Board may provide.

           (c) Sales Price. Subject to the requirements of applicable law, the Board shall determine the price, if any, at which shares of Incentive Stock or Shares underlying Restricted Stock Units shall be sold or awarded to a Participant, which price may vary from time to time and among Participants and which may be above or below the Fair Market Value of such shares at the date of grant or issuance.

           (d) Share Vesting. Except as set forth herein, the grant, issuance, retention and/or vesting of shares of Incentive Stock and Restricted Stock Units, as applicable, shall be at such time and in such installments as determined by the Board. The Board shall have the right to make the timing of the grant and/or the issuance, ability to retain and/or vesting of shares of Incentive Stock and Restricted Stock Units subject to continued service, passage of time and/or such performance criteria as deemed appropriate by the Board; provided that, in no event shall an award of Incentive Stock or Restricted Stock Units vest sooner than (i) three (3) years after the date of grant, if the vesting of the Incentive Stock or Restricted Stock Units is based solely on Continuous Status as an Employee or Consultant and the grant of Incentive Stock or Restricted Stock Units is not a form of payment of earned incentive compensation or other performance-based compensation, provided, however, that notwithstanding the foregoing vesting limitations, shares of Incentive Stock and awards of Restricted Stock Units vesting under this clause (i) may vest in installments so long as the vesting schedule, at any point in time, is not more favorable than what would be vested under a monthly pro rata installment schedule (i.e., 1/36 per month for 3 years), or (ii) one (1) year after the date of grant, if the vesting of Incentive Stock or Restricted Stock Units is subject to the achievement of performance goals. Notwithstanding the foregoing, the Board may accelerate vesting (in a Stock Award Agreement or otherwise) of any Stock Award in the event of a Participant’s termination of service as an Employee or Consultant, a Change in Control or similar event, provided that, in the case of award of Incentive Stock or Restricted Stock Units that is intended to qualify as “performance based compensation” under Section 162(m), such acceleration shall comply with the requirements set forth in Treasury Regulation Section 1.162-27(e)(2)(iii).

           (e) Transferability. Shares of Incentive Stock and Restricted Stock Units shall be transferable by the Participant only upon such terms and conditions as are set forth in the applicable Stock Award Agreement, as the Board shall determine in its discretion, so long as the Incentive Stock or Restricted Stock Units, as applicable, awarded under the Stock Award Agreement remain subject to the terms of the Stock Award Agreement.

           (f) Discretionary Adjustments. Notwithstanding satisfaction of any performance goals, the number of shares granted, issued, retainable and/or vested under an award of Incentive Stock or Restricted Stock Units, as applicable, on account of either financial

performance or personal performance evaluations may be reduced by the Board on the basis of such further considerations as the Board shall determine, but may not be increased. In addition, the Board may appropriately adjust any evaluation of performance under the Qualifying Performance Criteria to exclude any of the following events that occurs during a performance period: (i) asset write-downs, (ii) litigation or claim judgments or settlements, (iii) the effect of changes in tax law, accounting principles or other such laws or provisions affecting reported results, (iv) accruals for reorganization and restructuring programs and (v) any extraordinary non-recurring items as described in Accounting Principles Board Opinion No. 30 and/or in management’s discussion and analysis of financial condition and results of operations appearing in the Company’s annual report to stockholders for the applicable year.

           (g) Voting Rights. Unless otherwise determined by the Board, Participants holding shares of Incentive Stock granted hereunder may exercise full voting rights with respect to those shares during the period of restriction. With respect to Shares underlying Restricted Stock Units, Participants shall have no voting rights unless and until such Shares are reflected as issued and outstanding shares on the Company’s stock ledger.

           (h) Dividends and Distributions. Participants in whose name an Award of Incentive Stock is granted shall be entitled to receive all dividends and other distributions paid with respect to the Shares underlying such Award, unless determined otherwise by the Board. Participants in whose name an Award of Restricted Stock Units is granted shall not be entitled to receive dividends or other distributions paid with respect to the Shares underlying such Award, unless determined otherwise by the Board. The Board will determine whether any such dividends or distributions will be automatically reinvested in additional Shares or will be payable in cash; provided that such additional Shares and/or cash shall be subject to the same restrictions and vesting conditions as the Award with respect to which they were distributed. Notwithstanding anything herein to the contrary, in no event shall dividends or dividend equivalents be currently payable with respect to unvested or unearned Awards subject to performance criteria.

      11. Non-Transferability of Stock Awards. Except as otherwise expressly provided in the terms of the applicable Stock Award Agreement, a Stock Award may not be sold, pledged, assigned, hypothecated, transferred or otherwise disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Participant, only by the Participant or the Participant’s legal representative. Notwithstanding the foregoing, the Participant may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Participant, shall thereafter be entitled to exercise the Stock Award.

      12. Adjustments upon Changes in Capitalization or Change in Control. The number of Shares covered by each outstanding Stock Award, and the number of Shares which have been authorized for issuance under the Plan but as to which no Stock Awards have yet been granted or which have been returned to the Plan upon cancellation, expiration, forfeiture or other termination of a Stock Award, as well as the price per Share covered by each such outstanding Stock Award, shall be equitably adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split or the payment of a stock dividend with

respect to the Common Stock or any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustments shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to a Stock Award. Such adjustment shall be designed to comply with Section 409A and 424 of the Code or, except as otherwise expressly provided in Section 3(d) of this Plan, may be designed to treat the Shares available under the Plan and subject to Awards as if they were all outstanding on the record date for such event or transaction or to increase the number of such Shares to reflect a deemed reinvestment in Shares of the amount distributed to the Company’s securityholders.

     For purposes of the Plan, a “Change in Control” shall be deemed to occur upon the consummation of any one of the following events: (a) a sale of all or substantially all of the assets of the Company; (b) a merger or consolidation in which the Company is not the surviving corporation (other than a transaction the principal purpose of which is to change the state of the Company’s incorporation or a transaction in which the voting securities of the Company are exchanged for beneficial ownership of at least 50% of the voting securities of the controlling acquiring corporation); (c) a merger or consolidation in which the Company is the surviving corporation and less than 50% of the voting securities of the Company that are outstanding immediately after the consummation of such transaction are beneficially owned, directly or indirectly, by the persons who owned such voting securities immediately prior to such transaction; (d) any transaction or series of related transactions after which any person (as such term is defined in Section 13(d)(3) of the Exchange Act), other than any employee benefit plan (or related trust) sponsored or maintained by the Company or any subsidiary of the Company, becomes the beneficial owner of voting securities of the Company representing 40% or more of the combined voting power of all of the voting securities of the Company; (e) during any period of two consecutive years, individuals who at the beginning of such period constitute the membership of the Company’s Board of Directors (“Incumbent Directors”) cease for any reason to have authority to cast at least a majority of the votes which all directors on the Board of Directors are entitled to cast, unless the election, or the nomination for election by the Company’s stockholders, of a new director was approved by a vote of at least two-thirds of the votes entitled to be cast by the Incumbent Directors, in which case such director shall also be treated as an Incumbent Director in the future; or (f) the liquidation or dissolution of the Company.

     In the event of a Change in Control, then: (a) any surviving or acquiring corporation shall assume Stock Awards outstanding under the Plan or shall substitute similar awards (including an option to acquire the same consideration paid to stockholders in the transaction described in this Section 12 for those outstanding Options under the Plan), or (b) in the event any surviving or acquiring corporation refuses to assume such Stock Awards or to substitute similar awards for those outstanding under the Plan, (i) with respect to Stock Awards held by persons then performing services as Employees or Consultants, the vesting of such Stock Awards and the time during which such Stock Awards may be exercised shall be accelerated prior to such event and

the Stock Awards terminated if not exercised after such acceleration and at or prior to such event, and (ii) with respect to any other Options outstanding under the Plan, such Options shall be terminated if not exercised prior to such event.

      13. Miscellaneous.

           (a) Acceleration of Exercisability and Vesting. The Board shall have the power to accelerate the time at which a Stock Award may first be exercised or the time during which a Stock Award or any part thereof will vest in accordance with the Plan, notwithstanding the provisions in the Stock Award stating the time at which it may first be exercised or the time during which it will vest. If the Board, at its sole discretion, permits acceleration as to all or any part of a Stock Award, the aggregate Fair Market Value (determined at the time Stock Award is granted) of stock with respect to which Incentive Stock Options first become exercisable in the year of such dissolution, liquidation, sale of assets or merger cannot exceed $100,000. Any remaining accelerated Incentive Stock Options shall be treated as Nonstatutory Stock Options.

           (b) Additional Restrictions on Stock Awards. Either at the time a Stock Award is granted or by subsequent action, the Board may, but need not, impose such restrictions, conditions or limitations as it determines appropriate as to the timing and manner of any resales by a Participant or other subsequent transfers by an Participant of any Shares issued under a Stock Award, including without limitation (i) restrictions under an insider trading policy, (ii) restrictions designed to delay and/or coordinate the timing and manner of sales by Participants, and (iii) restrictions as to the use of a specified brokerage firm for such resales or other transfers.

           (c) Stockholder Rights. No Participant shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Common Stock subject to a Stock Award unless and until such Participant has satisfied all requirements for exercise and/or vesting of the Stock Award pursuant to its terms and said Shares have been issued to the Participant.

           (d) Investment Assurances. The Company may require a Participant, as a condition to exercising or acquiring Common Stock under any Stock Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of the Stock Award; and (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Stock Award for the Participant’s own account and not with any present intention of selling or otherwise distributing the Common Stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (1) the issuance of the shares of Common Stock upon exercise of the Option or acquisition of Common Stock under the Plan has been registered under a then currently effective registration statement under the Securities Act or (2) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates

issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock represented thereby.

           (e) Withholding Obligations. To the extent provided by the terms of a Stock Award Agreement, the Participant may satisfy any federal, state or local tax withholding obligation relating to a Stock Award by any of the following means (in addition to the Company’s right to withhold from any compensation paid to the Participant by the Company) or by a combination of such means: (i) tendering a cash payment; (ii) authorizing the Company to withhold shares of Common Stock from the shares of Common Stock otherwise issuable to the Participant as a result of the Stock Award, provided, however, that no shares of Common Stock are withheld with a value exceeding the minimum amount of tax required to be withheld by law; or (iii) delivering to the Company owned and unencumbered shares of Common Stock.

      14. Amendment and Termination of the Plan.

           (a) Amendment and Termination. The Board may at any time terminate the Plan or amend the Plan from time to time in such respects as the Board may deem advisable; provided, however, that no amendment shall be effective unless approved by the stockholders of the Company to the extent stockholder approval is necessary for the Plan to satisfy the requirements of Section 422 of the Code, Rule 16b-3 or any listing requirements of any securities exchange or national market system on which the Common Stock is traded.

           (b) Effect of Amendment or Termination. Any such amendment or termination of the Plan shall not adversely affect Stock Awards already granted and such Stock Awards shall remain in full force and effect as if the Plan had not been amended or terminated, unless mutually agreed otherwise between the Participant and the Board, which agreement must be in writing and signed by the Participant and the Company.

      15. Conditions Upon Issuance of Shares. Shares shall not be issued pursuant to a Stock Award unless the exercise of the Option, if applicable, and the issuance and delivery of such Shares pursuant the Stock Award shall comply with all relevant provisions of the law, including without limitation, the Securities Act, the Exchange Act and the requirements of any stock exchange or national market system upon which the Shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance.

      16. Liability of Company . The Company and any Affiliate which is in existence or hereafter comes into existence shall not be liable to a Participant or other persons as to:

           (a) The non-issuance or sale of Shares as to which the Company has been unable to obtain from any regulatory body having jurisdiction the authority deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder; or

           (b) Any tax consequence expected, but not realized, by any Participant or other person due to the receipt, exercise or settlement of any Stock Award granted hereunder.

      17. Reservation of Shares. The Company, during the term of the Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. The Company’s inability to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary for the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

      18. Stock Award Agreement. All Stock Awards shall be evidenced by written award agreements in such form as the Board shall approve.

      19. Choice of Law. The law of the State of Delaware, without regard to its conflict of laws rules, shall govern all questions concerning the construction, validity and interpretation of the Plan.

      20. Section 409A . It is intended that any Options and Incentive Stock issued pursuant to this Plan and any award agreement shall not constitute “deferrals of compensation” within the meaning of Section 409A of the Code and, as a result, shall not be subject to the requirements of Section 409A of the Code. It is further intended that any Restricted Stock Units issued pursuant to this Plan and any award agreement or other written document establishing the terms and conditions of the Stock Award (which may or may not constitute “deferrals of compensation,” depending on the terms of each Stock Award) shall avoid any “plan failures” within the meaning of Section 409A(a)(1) of the Code. The Plan and each award agreement or other written document establishing the terms and conditions of a Stock Award are to be interpreted and administered in a manner consistent with these intentions. However, no guarantee or commitment is made that the Plan, any award agreement or any other written document establishing the terms and conditions of a Stock Award shall be administered in accordance with the requirements of Section 409A of the Code, with respect to amounts that are subject to such requirements, or that the Plan, any award agreement or any other written document establishing the terms and conditions of a Stock Award shall be administered in a manner that avoids the application of Section 409A of the Code, with respect to amounts that are not subject to such requirements.

      21. Required Delay in Payment on Account of a Separation from Service . Notwithstanding any other provision in this Plan, any award agreement or any other written document establishing the terms and conditions of a Stock Award, if any stock Award recipient is a “specified employee” (as defined in Treasury Regulations Section 1.409A-1(i)), as of the date of his or her “Separation from Service” (as defined in authoritative IRS guidance under Section 409A of the Code), then, to the extent required by Treasury Regulations Section 1.409A- 3(i)(2), any payment made to the Stock Award recipient on account of his or her Separation from Service shall not be made before a date that is six months after the date of his or her Separation from Service. The Board may elect any of the methods of applying this rule that are permitted under Treasury Regulations Section 1.409A-3(i)(2)(ii).
